Wringer mop



May- 27, T93@ H. HERTZBERG WRINGER MOP Filed JlAlly 29, 1929 Patented May 27, 1930 PATENT @FF-ECE Y HARRY HEBTZBERG, OF BROOKLYN, NEW YORK WRNGER MOP Application filed .Tuly 29,

This invention `relates to wet mops, Aand more particularly'to mop heads which are intended to be mounted upon handles and which may be wrung by stretching the mop strands along the handle and twisting them around the same.

It is the object of the present invention to provide a mop head of this type which is of extremely simple construction, which can easily be released from the handle and which is attached to the lower end of the handle by resilient and yielding attaching means.

Vith these objects in view the invention consists in certain novel featui es of construcl'tion, combination of elements and arrangements of parts which will be fully described in these specifications and finally be pointed out in the appended claims.

The invention is shown in the accompany? ing drawings which form a material part of these specifications and in which:

Fig. 1 is an elevation of my wringer mop in stretched condition. A part of the mop strands is cut away to show the inner parts.

Fig. 2 is an elevation of the mop of Fig. 1 when the same is twisted for wringing.

Fig. 3 is an elevation of the mop of Figs. 1 and 2 when the same is in position for mopping.

Fig. 4 is a det-ail elevation of sleeve 12 parts of which are cut away to show the fastening of the mop strands thereto.

Fig. 5 is a detail showing the fastening of the mop strands at the lower end of the handle. The resilient connector 30 and tie wires are shown in section, and a part of the mop strands is removed to show the interior.

Referring to the drawings my wringer mop consists of a standard round mop handle 11 which is provided with a threaded portion 11a of smaller diameter at its lower eXtremity. The threaded portion 11a of the handle is enclosed within a helical coil-spring 30 of wire, wound to have the same pitch as the threads on 11a and with a more closely wound portion of smaller diameter extending beyond the bottom 11c of the mop handle. In this manner the turn 30b of the coil provides a shoulder within the coil, forming a stop 1929. Serial No. 381,949.

for the mop handle, so that the upper part K of the spring acts like a screw-socket with closed bottom, for the mop stick. On the outside of the coil turn 30a, being of larger dia-meter than 30b forms also a shoulder 0n the outer face of the coil. n n The mop material Aconsists preferably of rope-like strands which are folded upon themselves at their middle parts for forming loops. These loops are tied by tie wires 1Ba and 13b to a preferably wooden sleeve mounted to slide on the mop handle 11. Sleeve 12 is provided with two encircling grooves of saw-tooth shape providing two transverse shoulders 12a and 12b into which the mop strands 2O are pressed by the tie wires 13a and 13b. lt will be seen from Fig. 4 that only one layer of mop material is passing through the grooves for 13a and 13b and that the outer layer of mop cords covers the tie wires. `By this manner of fastening a very close contact of cords and sleeve andl an eX- tremely strong joint, which resists thepulling and twisting better than other methods of fastening,`is provided. l

The ends ofthe mop strands are tied together by a tie wire ring 14h below the end of the coil spring at 30c and fastened to the coil at the shoulder 3()a by a tie wire 14a which presses the cords into the space between turns 30a and 301 and thereby produces a. very tight connection at that point. If tie wire ring 14a is somewhat loose, the lower part of the coil can be screwed into the hollow part of the ball-shaped mop cords until the bottom-turn 30c presses the cords against the upper face of ring 14h, stretching the ball longitudinally into oval shape until the shoulder at 30EL prevents further movement, then wire 14Ca is closely tied by twisting the ends about each other. The part of the coil from 3()a downward provides a resilient center for ball 20a which is a very desirable feature as the side of the ball and not only the front edge of the mop stick can be pressed against the looped cords of Fig. 3 and against the floor surface while scrubbing.

It is obvious that the aboveV described mop can be wrung by turning the sleeve A12 on handle 11 and thereby twisting the mop cords around the latter.

The very few and simple parts which enter in the construction of this mop permit its manufacture and sale at an extremely low price and in addition provide an implement which embodies valuable novel features.

Obviously the invention is susceptible of modification and arrangement of parts, and the right is herein reserved to make such changes as fall within the scope of the appended claims without departing from the spirit of the invention.

Having thus described my invention what l claim is:

1. A wringer mop comprising in combination a mop handle, a thread on one end of said handle, a helical coil of Wire adapted to env gage the threads on said handle, said coil extending beyond the end of said handle, a sleeve rotatably and slidably mounted on said handle and mop material having one end attached to said sleeve the other end covering said wire coil beyond the end of said handle, forming a flexible extension to said handle enclosed within mop material.

2. A wringer mop comprising in combination a mop handle, a helical coil of wire attached to one end of said handle providing a flexible extension on said handle beyond the end thereof, said coil having a shoulder pressing said material against said shoulder inhibiting longitudinal movement of said material on said coil.

5. A wringer mop comprising in combination a mop handle having a thread on one of its ends, a helical coil of Wire engaging the HARRY HERTZBERG.

formed in its outer face by the turns of said y coil, a sleeve rotatably and slidably mounted on said handle and mop material attached to said sleeve covering said coil, a ring tying said mop material against the shoulder of said coil beyond; the end of said handle and a second ring uniting said material beyond the end of said coil forming a soft and fiexible extension on said handle.

3. A Wringer mop comprising in combination a mop handle, threads on one end of said handle, a threaded socket in engagement with the threads on said handle, a coiled spring on said socket extending beyond the end of said handle, a sleeve slidably and rotatably mounted on said handle, mop material tied to said sleeve and to lie against the outside of said coil spring to cover the same, the turns of said spring providing a yielding support for said mop material and forming means to prevent rotary motion of said mop material on said spring.

4. A wringer mop comprising in combination a mop handle having a thread on one of its ends, a helical coil of wire engaging the threads on said handle and extending beyond the end thereof the thread engaging turns of said coil being of larger diameter than those beyond said handle providing a shoulder and a flexible extension on said handle, a sleeve slidably and rotatably mounted on said handle, mop material attached to said sleeve and to the cylindrical outside of said flexible extension covering the same and a tie wire ring
